  • Secure 3D printing
    Patent number: 11263296
    Abstract: A computer-implemented method for controlling reproduction of an item represented by a digital asset stored in a trusted computing environment using a reproduction device in an untrusted computing environment, in which a succession of data seg¬ments is transmitted from the trusted computing environment to the untrusted computing environment, the succession of data segments comprising segments of reproduction data, each of which includes at least one instruction for controlling the reproduction device to reproduce a portion of the item, and at least one segment of obfuscation data which has a structure identical the reproduction data but is incapable of controlling the reproduction device to reproduce a portion of the item, the method comprising: a) determining whether the next segment of data in the succession should be a segment of reproduction data or a segment of obfuscation data; b) where the next segment of data should be a segment of reproduction data, selecting and extracting an unprocessed segment of
